Apple iPad mini 2 is a nice tablet. It comes with good 7 inch screen with HD resolution. 512 mb ram and 0.2 megapixel back camera and a large 6300 mah battery. Battery last more than a month in standby mode which is quite good. It is a unibody tablet so that you can't remove battery.
I am not satisfied with the camera performance of this tablet. Apple is known for its camera but here it is wrong. You can't make cellular calls from this tablet. Even there is Sim slot. But it is only for data access.
